From my basic Korean understanding (some things could be wrong):
TJ goes back for KG and gets mad he didn’t take the bus or taxi. KG says he didn’t have money (?).
Back home, TJ is convinced there’s something going on with KG and wants him to talk about it, KG brushes him off
In bed, TJ asks KG to hug him “like mom” and KG reminds him that he’d asked him to stop.. TJ tells KG he’s sad.
On the bleachers, TJ asks where their other friend is when Hyemi comes over and asks KG to hang out that night
TJ complains that she’s over talking to them and accuses her of having no friends, she admits he’s right (KG gives TJ the “what wrong w u” face)
Hyemi tells TJ he’s not all that (?)
During dodgeball, Chanmi asks KG to protect her and KG says he will, since he’s a real bodyguard. This annoys TJ.
After the game, KG asks if TJ’s head hurts
TJ reminds KG he’s his bodyguard, and gripes about something KG says that I can’t understand
KG apologizes for the game, but TJ asks why, since it was just a game. (KG: “Exactly.” TJ: “It’s just a game, but why am I so angry?”
TJ pushes him down, and KG asks if they’re going to do this here? TJ wonders what he thinks they’re doing? KG stutters that they should go to the Dojang to spar, but TJ basically tells him not to pretend, because it’s suffocating.
I think TJ then says he thinks he and KG are the same, so it’s more suffocating, causing a freaked out KG to tell him to get off
